SASH-BALANC'ING DEVICE.

FBPECIFIGATION forming part of Letters Patent No, 321,035, dated June30, 1885.

Application tiled October 22, 1984. (No model.) Paten ed in England May29. 1884, No. 8,373.

T0 at whom it may concern:

Be it known that l, HUGH JoNEs, manager of the Patent \Vindow FittingsCompany,(lim iled,) a subject of the Queen of Great Britain,

and a resident of the city of Liverpool, in the county of Lancaster,inthat part of the United Kingdom of Great Britain and Ireland calledEngland, have invented certain new and useful Improvements in Apparatusfor Balancing and Securing Sliding Window-Sashes,(for which I haveapplied for Letters Patent for Great Britain, No. 8,37 3, bearing dateMay 29, 1884; and I do hereby declare that the following is a description of my invention in such full, clear, concise, and exact termsas to enable any one skilled in the arts to which it appertains or ismost nearly connected to put into practice and use the same, referencebeing had to the accompanying sheets of drawings, and to the letters andfigures of reference marked thereon, like letters and figures being usedto denote the same-or corresponding parts throughout the various viewsin the drawings.

This invention relates to that class of sliding window-sashes which arebalanced by weighted racks and pinions, and provides means of securingsashes in any open or in a closed position, means for guiding thesashweights and keeping them up to the pinions, and means for gainingaccess to the weights and pinions.

This invention, therefore, consists in the novel construction andcombination of parts,

as will be hereinafter more fully described,

and specifically pointed out in the claims.

In the accompanying drawings, forming a part of this specification,Figure 1 is a plan showing the improvements according to this inventionapplied to a window-sash. Fig. 2 is an elevation in section through theline X X, Fig. 1. Fig. 3 is afront view of Fig. 2. Fig. at is aperspective view of divided stileboard.

Referring to the drawings, Aare the sashes of the window. C is thestile-board of the H is a spindle, which The racks in the windows-ashare formed as follows: A longitudinal groove, L, is cut in the edge ofthe sash, and wooden pins K are driven into the window-sash and throughthe groove L, and so form the rack.

The racks in the weights are made as follows: 5 5 The weights F areformed with a longitudinal groove, M, and wooden pins N are driventhrough the weights and through the groove M, so forming the rack. Thepins N are made to project at each side of the weight F, so as to bearagainst bars P, provided for the purpose, and which are made to guidethe weight F. The pinions Jtake into the teeth K andN of the window-sashA and weight F, respectively. The pinions Jrun loose on the spindle H,and on the spindle H and outside each of the wheels J there are providedrectangular nuts Q, which work on right and left hand screw-threads B,cut on the spindle H. The nuts Q bear and work in a rectangular seat, q,cut out of the top of the lower portion of the stile-board C. Thespindle H is borne at its center 'portionnamely, between the pinions J;also by the stile-board C, at h, which is cut away at the back, butcarried up in front at h to meet the upper portion of the stile-board C.On the spindle H, and outside the nuts Q, are the washers S, fixed onthe spindle H. The inside end of the spindle H is square at H to receivea key, T,which is used for fastening and unfastening thesashes.

To fasten the sashes, the key T is placed on the square portion H of thespindle H, and the spindle H is turned by the key T, so as to bring thenuts Q toward each other, and so 8 5 press the pinions J against thesides of the racks of the sashes and the weights, thereby causing thesashes A to bind on the separating-bar D and the weights F to bind onthe center bar, P. Q0

To free the sashes, the spindle H is turned back until sashes andweights become released.

To enable the weights F, pinions J, and the spindle H to be placed inposition and to be accessible for repairs or other purposes withoutremoving the sashes and disturbing the window-frame, I divide theStile-boards C at C, so that when both sashes are at the bottom of thewindow-frame the upper portion of the stile-board G,with the upperportion of the separating-bar D,can be removed without disturbing thelower portions. To secure the upper portion in position, I use bolts U,one of which is placed as shown in the drawings, and others beinginterspaced above, according to the size of the window. By withdrawingthe bolts U the upper portion of the stileboard C can be removed, andafter removal improved means for securing the sashes in any open or in aclosed position provides a simple and effective method of fastening thesashes and of preventing the rattling of the sashes caused by wind orother causes. By dividing and constructing the stile-boards as hereindescribed, the weights and pinions and fastening mechanism can bereadily placed in po sition or removed while the window-sashes are intheir places.

I am aware that weighted racks and pinions have been used prior to myinvention as a means for balancing window-sashes, and that keys havebeen inserted in various ways to lock the racks and pinions,and so thesashes, and I do not lay any claim to the use of these mechanisms; but

\Vhat I claim as my invention is- 1. A window-sash having a rack on itsedge formed by a groove, L, and wooden teeth K, in combination with ametal pinion, J, and a weighted rack, F, )rovided with a groove, M, andwooden teeth N, which .project and form a guide with the bars P for theweight, substantially as and for the purposes set forth.

2. The combination of the spindle H, having a right-and-left-hand screw,R, and nuts Q, whereby through the pinions J the sashes A, and also theweights M, are caused to bind against the separating-bar D and centerguide, 1?, substantially as set forth, and as shown in the drawingshereto annexed.
